BlueOptics SFP5141BU2MKB InfiniBand fibre optic cable 2 m MPO 4x LC

The BlueOptics SFP5141BU2MKB is a 2 m InfiniBand fibre optic cable designed for high-density network interconnects. It features an MPO connector on one end and four LC connectors on the other, provides full duplex transmission and uses G.657.A2 single-mode fibre with a 125 µm core diameter. Intended for short to medium reach links within data centres and server rooms, this cable supports reliable, low-loss optical connections for InfiniBand environments and similar high-speed networks.

Advantages

This InfiniBand fibre cable combines a compact MPO interface with standard LC terminations to simplify connections between MPO trunks and LC-equipped transceivers. The use of G.657.A2 fibre improves bend performance compared with older single-mode types, reducing risk of signal degradation in dense cabling routes. Full duplex transmission ensures simultaneous bidirectional data flow, and the 2 m length offers a balance between flexibility and minimal excess slack in rack- and cabinet-level deployments.

Suitable for

• Interconnecting InfiniBand switches and host channel adapters in data centres
• Linking MPO trunk cables to LC-based transceivers and patch panels
• Short-range server-to-switch and equipment-to-equipment optical connections
• High-density cabling environments where space and bend performance matter

Key specifications

• Length: 2 metres
• Connector types: MPO (one end) and 4 × LC (other end)
• Fibre type: G.657.A2 single-mode
• Core/cladding diameter: 125 µm
• Transmission mode: Full duplex
• Intended application: InfiniBand and high-speed optical networking

How to use

Before installation, verify transceiver compatibility and the required polarity for InfiniBand links. Route the cable following rack and cabinet pathways, avoiding sharp bends and crush points; the G.657.A2 fibre tolerates tighter radii but standard bend-radius practices still apply. Connect the MPO end to an MPO trunk or cassette and the four LC connectors to the corresponding LC ports on transceivers or patch panels, ensuring correct pair mapping for duplex channels. Secure the cable to prevent movement and perform optical verification with appropriate testing equipment after connection.

Usage recommendations

Store and handle the cable in a dry, dust-free environment. Use dust caps on connectors when not in use, and inspect endfaces for contamination before making connections. For best results in data centre deployments, keep cable runs neat, label both ends, and validate links with an optical power meter or certified fibre tester.
